extract kindsys to external library (#64562)
* extract kindsys

* reinstate kindsys report

This may end up living somewhere else (or not! who knows!), but the important part is that I don't get rid of it right now :)

I hate the package layout (kindsysreport/codegen) for the main function and will take pretty much any alternative suggestion, but we can change also change it later.

Note that the generated report.json is in a different location - anything using this (ops something) needs to be updated.
